Is it possible to use conditions in email content like we use in the build section?

Hi,

I am trying to update the content of an email that is sent to recipients after submission. Is it possible to use conditions in email content like we use in the build section of jot form?

You can conditionally send an email, but the content can only be changed in the email settings/tab.

Please note that the form won't resend the email to your existing submitters once you update the email template. To resend, you will have to access the submissions page and edit the submissions one at a time.
